0002803: Actor Hits Floor CTD
I've ran into this bug while making a map.

I've setup 2 teleporters with Actor Hits Floor trigger. However if you drop on the teleporter from a height greater than your jump height, Zandronum will crash to desktop.
I've made a test map to quickly reproduce this.

1) Get high jump rune
2) Jump over one of the teleporters and land on it, or alternatively, drop from the 3D floor placed in the map
3) The landing should make Zandronum crash to desktop

No tags attached.

Your map basically has the two teleporters linked together. The teleporter first teleports the player to the other teleporter, which then teleports the player back to the first one, which teleports the player back to the other one, etc.

This was already ruled out as a can't fix by ZDoom.

ZDoom has now added a compatibility flag, compat_teleport, for this.

For the record, both 2.1.2 and 3.0 crash with the example wad.

Is the flag going to be backported or do we need to wait for the 4.0 merge?
